Strangers discovering they have an uncanny doppelganger have hit the headlines this week - and now you can track down your own.

Neil Douglas, 32, from Glasgow, became a viral sensation when he took a selfie with his spitting image, a mystery Londoner, on a Ryanair flight from Stansted to Galway.

Astonishingly, they say they met when one found the other sat in his seat.

When the bearded pair arrived in Ireland they discovered they were booked in the same hotel and apparently decided to go for a pint together.

But they're not the only lookalikes to have met recently - in fact the website Twin Strangers , based in Ireland, actively brings people together.

The site was set up by Niamh Geaney, who found her first doppelganger after two weeks, after Niamh and her friends challenged each other to find their ‘Twin Strangers’, anywhere in the world, in just 28 days.

Irish student Ciara Murphy and Cordelia Roberts, from the UK, met in Bremen in Germany and snapped a selfie which quickly went viral on Facebook.

And American pair Ambra, 23, from Fayetteville in North Carolina and Jennifer, 33, from Spring in Texas, were also brought together by the site.

All you have to do is register, post a picture and tick off a list of facial features and a gallery will appear showing a list of likely canditates for your long-lost twin.
